Leprosy and tuberculosis in Iron Age Southeast Asia?

The recent excavation of a sample of 120 human skeletons from an Iron Age site in the valley of the Mun River, a tributary of the Mekong River on the Khorat Plateau in northeast Thailand, has provided the largest sample from this period in the region to date. This paper reviews three individuals from the sample with pathological changes for which the differential diagnosis includes systemic infectious disease. In two of these, both males with lesions of the hands and feet, leprosy and psoriatic arthritis are discussed as differential diagnoses, with leprosy the most probable. In the third, a female with lesions of the spine, the differential diagnosis includes tuberculosis and nonspecific osteomyelitis. Tuberculosis is the most probable diagnosis. Although the focus of this paper is a presentation of the evidence for infectious disease at Noen U-Loke, the significance of probable diagnoses of mycobacterial diseases for the history of the diseases and for prehistory in mainland Southeast Asia is also briefly discussed.
